What Kind of Board is This? Retro 1980's Surfboard

Hey this used to be my uncle’s surfboard. It has been sitting in a shed for years. It has the name Pro Series on the front and back. Single Fin. No other words/markings. Anyone have any ideas?

I think that might be a Natural Progression ghost logo. They were a shop in Pacific Palisades (Santa Monica) area.

You think it’s worth anything?

It’s hard to say from that one photo. It might be worth a couple hundred bucks? Maybe a bit more? Robbie Dick and Dean Edwards (+others) were shapers there and Jay Riddle was a team rider. I remember seeing Miki Dora riding a NP at Malibu once but don’t know if he was officially ‘on the team’ or anything. A guy named Terry Lucoff was one of the owners. Rumor had it that he was heir to the Mattel Toy throne(?) That’s all I can remember off the top of my head.

Thank you!

More photos would help, a lot.
Like, maybe a photo of what little labelling there is?

Looks like it’s in good shape.
I’d surf the thing. (But I have a soft spot for single-fins.)
